| Abstract: | The purpose of the paper is to systematically describe the background, main processes, technical methods, assessment results, and applications of the investigation and assessment on quality grade of cultivated land in China. Methods employed are inductive analysis, comparative analysis and statistical analysis. The paper summarizes that the cultivated land can be categorized into 15 quality grades in China. The average quality grade is 9.8, which shows the quality generally is low. It is concluded that the research provides a first-time work on the investigation and assessment of cultivated land quality grade and its distribution in China. It also provides necessary supports for achieving a management mode of quantity and quality-oriented simultaneously. |
